How long after surgery can symmastia occur? Am I developing it? (photos)

Hello,Thank you for the question and photos. You do not appear to have synmastia. If you have concerns about breast appearance and placement i recommend that you see your Plastic Surgeon for an exam.All the best 

You do not have symmastia as evidenced by the clear separation of the implants on the medial aspect.  You likely will not develop it in the future.  Best wishes, Dr. T.
